Equipment Settings 61
Flow mode (only available when SL3000XL sniffer line is connected)
In this submenu the Protec P3000XL can be switched between
LOW FLOW mode and
HIGH FLOW mode.
Default setting:
HIGH FLOW Mode
Limits low flow error
This submenu is only available if the
ADDITIONAL LOW FLOW ERROR is set to ENABLED.
In this submenu the limits for the
ADDITIONAL LOW FLOW ERROR may be set-up. If the
actual flow through the sniffer line drops below the
LIMITS LOW FLOW ERROR, the
Protec P3000XL will stop measuring. Only when the cause of the low flow problem
has been resolved and the flow is above the
LIMITS LOW FLOW ERROR again, the
Protec P3000XL will go back into measurement mode.
Two different values for the HIGH FLOW and LOW FLOW mode may be entered.
The value for the HIGH FLOW mode will also be converted into a corresponding
LOWER PRESSURE LIMIT. If the corresponding LOWER PRESSURE LIMIT is
undercut, this is an indication of the smaller capillary's flow being blocked in
SL3000XL sniffer line and also E55 / E56 will be issued and the Protec P3000XL will
stop measuring.
Error limits can be set to values between 150 and 240 sccm for LOW FLOW mode
and to values between 1500 and 2400 sccm for HIGH FLOW mode.
Sniffer button
In this submenu the use of the right sniffer button for switching between
LOW FLOW
and HIGH FLOW mode during leak testing (except when in IꞏGuide mode) may be
ENABLED or DISABLED. If the use of the SNIFFER BUTTON is DISABLED, the Protec
P3000XL may only be switched from
HIGH FLOW to LOW FLOW mode (or vice versa)
through the
FLOW MODE submenu or via RS232.
Default setting: enabled
